I agree with you. People have been hating so much on hoarders, while not acknowledging that the real problem is that people are way too reliant on a just-in-time supply chain. It's really not that difficult, expensive, or space-consuming to have a buffer of at least one month for scenarios like this. Yet, most people don't build up this buffer over time, out of laziness, and then they go around blaming others for the shortages during a crisis (or they go panic-hoarding themselves).
